Lawnnucnpnunfsn, or oovme'roiw, KENTUCKY,

Be it known that I, LAWRENCE BRUDER, a citizen of the United States; residing at Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Dumping- Vehicles, of which the following is a specification.

My inventionrelates to that classof vehicles, the bodies of which are adapted to be dumped and more particularly to the specific means whereby the body can be rotated and dumped at any desired position upon the truck or chassis.

The object of my invention is to provide a ,vehicle with eificient,. durable, and inexpensive means whereb the body of said vehicle may be rotated in a horizontal plane upon the vehicle truck and may be dumped in any position which it isthereby adapted to assume. This is a great advantage especiall to trucks adapted to carry coal inask muc as the can be driven right up to and parallel wit the curb and dumped if d siredwithout having to back the truck up to thecurb and thereby interfere with traflic on 'thestreet.

A further object of my invention is to construct a vehicle body having dumping means-which enables the body to be raised higher than the ordinary dump body without increasing the height of-the frame (car rying the operating mechanism.

My invention consists broadly in the combination with a vehicle body of means whereby it is adapted to be raised at the forward I end, said means consisting of lifting arms" erated in a vertical plane, said lifting arms adapted to be horizontally disposed under the vehiclebody when said body is in its lowered position, and means for exerting whereby they prythe vehicle bodyupward at the forward end, said lifting arms engaging the base upon which the body is the lifting arms are limited in their ment relative to the vehicle body..

' Myinvention consists further in that arrangement nd combination of parts as will be describe in the-following specification and pointed out in the appended claims. 1 Inthe drawings: Figure 1 is a side elevational view of a motor truck equipped invention; Fig. 2 is a detail side move- Y I L Specification of Letters Patent.

elevational view of the lifting arm; Fig. 3 is a front elevational view of same; Fig. 4 is a sectional view showing the body turned ninety degrees on the truck frame Fig. 5 is and operating mechanism; and Fig. 6 is a truck. I

Referring more particularly to the drawings, 1 illustrates a truckframe shown as the frame of a motortruckand, 2 the stationary frame securely fastened thereto in any desirable manner. The stationary frame or base 2 is provided with a bearing ring 3 bolted' thereto and a plate 4 provided with a lug or pin 5 near the center thereof. A rotatable frame 6 (best shown in Fig. 5) is adapted to be placed on the frame 2 and is provided with aplate 7 having a a perspective view of the rotatable frame socket 8 therein into which the lug 5 on 1 the bearingon bearin rings 3 and 9. The f erably constructed of' rotatable frame is pre hard-timber and has two vertical posts 10 at the forward end between which a series of shafts 11 extend having their journals on the said posts. .These shafts carry a series of gear wheels 12 which are properly graduated in si e and proportioned to render the.

raising derload.

The upright posts 10 are properly braced by braces 13,which also serve to prevent the .body 14 from shifting its position relative to the'rotatable frame 6 when said body is down. The frame 6 may also be reinforced by. a strip orband of metal 15 extending around same. The rotatable frame 6 is further provided with two retaining arms 16 of the body comparatively easy unone on each side at the rear end of said rovide'd with a slot 17 through which a ho t 18 extends. The bolts 18 are fastened to the vehicle body a suit- I A able distance from the rear end to form 'a pivotfor the body when being dumped. When the rear end of the body has been raised high enough tost-rike the frame 2' of the'truck it can be raised higher if desired at whichtime the body pivots at. the point of contact with the frame 2 and the bolts 18 ride up in the slots 17 in the retain- V ing arms 16. However, it is seldom required to raise the body that distance.

The vehicle body 14 is provided with two lifting arms 19 pivoted at 20 to straps or brackets 21 mounted on the vehicle body 14. These straps or brackets are braced to the body by bracing arms 22 thereby forming a strongand secure pivot for the lifting arms. These l fting arms are preferably -made as shown in Fig. 3 with two parallel arms connected at the top or pivotal point. The connected port-ion 19 is provided with a hole'to receivea shaft or bolt 23 which bears in-the st-rapsorbrackets 21. The connected portion is also provided with a flange to x guide the chain or flexible connection 24 and which tends to keep it from moving laterally. A roller 25 is provided at the bottom of lifting arms 19 which is adapted or swing under the body 14 as best shown in Fig. 4, the arms 19 being so held and positioned as to fold or swing backwardly when they engage the tracks 26 on the movable frame 6 while the body is being lowcred. Sufficient space is left between the frames 6 and the body frame to allow the lifting arms to rest therebetween comfortably. The link arm 28 is provided to prevent the chain from tangling and becoming bulky under the vehicle body when the lifting arms are folded under.

A drum 30 is provided near the top of the upright posts 10 over which the flexible connection 24 is adapted to pass. The flexible connection is then brought down and connected to the shaft 12 by means of eye bolts 31. .When'this shaft 12 is rotated the flexible connection 24 is wound upon same and pull exerted on the lifting. arms which raises the vehicle body.

The lowermost shaft 12 is provided with a squared end upon which a handle of any suitable constructure is placed to turn it and thereby raise the body. The shaft 12" may also be provided with a square end to allo the body to be quickly lowered.

The operation of the device is as follows: hen the shafts 12 are operated the chain or flexible connection 24- is wound up on the shaft 12 after first passing over the drum 30. The lifting arms being at rest under the vehicle body are gradually pulled out, the pull being exerted at the roller or free ends of the lifting arms through the linkarm 28. When this occurs the lifting arms gradually pry the vehicle body up by the rollers engaging the tracks 26 until the chain 27 becomes taut, then the rollers 25 at the end of the lifting arms begin to rise oil the tracks 26 and the body continues to rise arm corresponding to the dotted line 32 and the other arm corresponding to the chain 24 the pull being exerted at the end of the latter. The lifting arm would then be connected to the middle of the toggle at the point where the rollers 25 are and it is seen would raise the body when the toggle was forced to straighten. This lifting arrangement is a decided advantage over the lifting devices now in use as it is a strong and durable device which does not requlre a tall ugly frame for the operating mechanism in order to raise the body to its uppermost position. The movable frame is provided with a socket 33 situated directly over a socket 34 on the stationary frame 2 so that a pin 35 can be inserted through both to lock the movable frame in normal position. A chain 36 is fastened to the vehicle body and is adapted to extend forwardly to the shaft 37 mounted on the stationary frame 2. This shaft has a squared end so that the handle which operates the shafts 12 and 12 can be used to operate it. The chain 36 is suitably fastened to said shaft when it is desired to swing the body and the shaft is then turned and winds up the chain which swings the body. This is necessary when the body is under a heavy load.

ile my invention is shown applied to a motor truck it can readily be applied to any corner of the stationary frame. These plates tend to act asblocks to give the frame a larger bearing than just the bearing rings 3 and 9 when it is in'its normal lowered position.

Many modifications of my invention might be made without departing from its spirit and scope and I do not wish to be confined to the exact details shown.

I What I claim as new and desire to secure by Letters Patent is:

. In combination with an automobile truck, a rotatable' frame thereon, having an upwardly extending portion atits foreend, a series of shafts mounted therein, a series of gear wheels on said shafts, a drum at the top of said vertical extension on said frame,

retaining arms at the rear end of said m tatable frame adaptedrto retain a body in position on saidframe, lifting arms at the foreend of said body adapted to extend under said body, a link arm fastened at the end of said lifting arms, a flexible connection at the end of said link arm adapted to Wind on said drum on the rotatable frame, and. tracks on said rotatable frame adapted to be engaged by said lifting arms to cause said lifting arms to fold under said body when 10 the body is lowered, substantially as and for the purposes set forth.
